(C1. ass-55) This invention relatesto a bumper-construction struction which is closed all aroundits sides very and more specifically to the construction and arsubstantially. j rangement of the pivotally connected ends of A slot 13 is provided in said barrel-shaped terbumper bars of the single front or impact bar 'minal about centrally of the. height thereof f and, a

bar and the construction being particularly Referring to Figs. 3 and 4 front or impactfbar' adapted for the so-called singlebarjtype. Front 10'v is the same as that 10 of F g.1; and barrelor impact bar 10 has its end coiled around rears'haped portion 12 is the sameas portion 12' of wardly to form a terminal. portion 12 which is the same figure. The differences betweenthe LL barrel-shaped due to the" fact that the impact modification of Figs. 3 and 4 .afnd that of Figs. 105

bar has an arcuate or curved cross section; name- 1 and 2 are particularly apparent in connection 1y, aconcavo-convex section as is apparent from with the rear bar'll'; Thisbar is provided-with Fig.1. The extreme end of the bar is bent around a reduced portion'14 which is bent around in into substantial contact with the rear concave a direction opposite to the corresponding porsurface of the impact bar, thus providing a con tion of the front bar'to form a terminal cylinder 11 assembly, said slot being narrower than, the

14". as is apparent, but it is to be understood that 'sary. In the form shown, however, there is such a reduced portion and also shoulders 14a analogous to the portions 14 an'dlia of bar 11 of Fig. 1, with the distinction b'eing noted that the reductions are accomplished in a somewhat different manner. Slot 13' in barrel-shaped ,portion 12v is wider than that shown inFig. 1 but this is a matter of conforming the construction to the sizes of the bars used inthe particular embodiment. In other respects, the construction of Figs. 3 and 4 is similar to that of Figs. 1 and 2 and the identical means is used for assembling the bar ends in operative assembly. In this modification also, I may if I so desire extend the 7 slot to the edge of the bar which contacts with i the rear concave surface of the impact' bar 10'.

It is clear from the foregoing that I have provided an extremely simple bumper'end construction which is at the same time proportionately strong and efficient and which providesznaxir mum protection against the elements thereby preventing reduction of efficiency. In practice, the slots define the limits of movement of the rear bar'and guide such movement which takes place upon impact or upon the existence of other than normal conditions.

It is clear that I am not limited to a concaveconvex impact bar but other suitable configurations are-equally well'adapted to the invention; nor am I limited totheparticular, size and relationship of the slots'shown as such would, of course; be changed to meet varying conditions to be met and to enable the use of the present invention with all sizes and shapes of front and rear bars. skilled'in'the artfrom the preceding descrip'- tion.

While I have described and illustrated for each modification only one end construction, it is to be understood that the other end construction 'is"identical therewith, except insofar as it is.

essentially of opposite hand.

' What I claim as new and desire to secure by Letters Patent is:

1. In a bumper construction, an impact bar having an end bent around into a hollow, substantially'clos'ed terminal, said terminal having a slot through one wall thereof, a rear bar having an end' passing through said'slot into the interior ofsaidqterminal, and means for pivotally connecting the indicated members in operative assembly, said means terminating. within said terminal 'which, accordingly, covers and protects the same.

2. In a" bumper construction, an impact bar having an end'bent around into a hollow, substantially closed terminal, said terminal having a slot through one wall thereof, a rear bar having anendpas sing through said slot into the interior of said terminal, and means for pivotally connecting the indicated members in operative height of said rear bar, the end of which is 'ac- .cordingly configured to enable it to passthrough the slot, and the terminal .being so constructed 'as, to receive the lower endof said pivotal con- Such will be understood by those one of its ends, the eye being cut away to form a transversely-extending slot through one wall thereof, a back bar having .a flattened end extending through said slot, and means for securing the said bars together. i

4. Bumper structure comprising an impactreceiving bar having a cylindrical eye formed in one of its ends, the'eyebeing cut away to form a transversely-extending slot through" one wall thereof, and a back bar of substantially flat material having an end twisted to a plane substantially at right angles to the remainder of said bar and extending into the said slot, and means for securing the said bars together. I

5. Bumper structure comprising an impactreceiving bar and a back bar, one of said bars having an end provided with a horizontally slotted eye, and the adjacent end of theotherbar extending through' the said slot and into the interior of said first bar end, and means for securing the bars together, said means terminating within and being enclosed by said dotted end which is of a size to receivethe same.

6. Bumper structure comprising an impactreceiving bar having a cylindrical eye formed in one of its ends,;the eye being cut away to form a transversely-extending slot through one wall thereof, a back bar having a flattened end with .an eye'therein extending through said slot, and '65 means comprising a bolt of shorter length than the said cylindrical eye for securing the said eyes together. i J

'7. Bumper structure comprising an impact receiving bar having a cylindrical eye formed in one of its ends, the eye being cut away to form'a transversely-extending "slot through one wall thereof, a backbar having a flattened end with an eye therein extending through'said slot, and means comprising a 'bolt of shorter length then the said cylindrical eye for securing the said eyes together -the head of the bolt engaging the upper end of the first-named eyejandthe shank of the bolt terminating at a point below the'secondnamed eye. H

8. In a bumper end construction, an impact bar, an eye at'the end of said impact bar. a cutout portion forming a'slot and a shoulder-on the inner sideof said eye, a rear bar having an end portion twisted through an angle of approximately 90, the twisted portion of said rear bar extending through the slotin said eye; said end portion having a holetherein, a bolt shorter than said eye and havingv a head engaging and closing the-upper end of said eye, said bolt extending through the hole in' said rear bar, a nut 'on'said bolt, saidnut and; bolt cooperating toclamp said bars and the head of the bolt in position;

9. In a bumper construction, an impact bar having an end'bent around into contact'with W itself to form a substantially closed cylindrical terminal having a slot through one wall thereof,

a rear bar of. greatervertical'height than said slot but having an apertured end reduced and passing through said slot into th'einterior of said terminal, a; bolt having ahead about the diameter of, said terminal and af'shankv extending nearly through said terminal and throughthe apertured end of. said rear bar, terminating. however, within said terminal and provided with suitable positioning and. fastening means f also lyingwithin said terminal.
